The problem might be not enough weight on the damper lever to pull the damper 
felt down on the string to get it to stop the vibrations. You can check this 
by lightly putting your finger on the damper head, and see if it solves the 
problem. 

If this is indeed the problem, then the solution is to add weight to the 
damper lever. This, I believe, should be considered a warrantee situation. 
You need to convince not only the dealer, but also Young Chang, that they 
need to take care of the problem. 

If they are washing their hands on it, advice the customer that she has a 
legal battle on her hands, and "walk away." Only get involved is she is 
willing to pay you for professional services. Do not attempt to make any 
repairs, without authorization from Young Chang.
